Abstract
Apparatus for use in cooling and/or drying or cleaning elongate material, such as drawn wire, tube or strip material, the apparatus comprising a chamber, which may be formed at least in part by a flexible tube, having an inlet and an outlet through which the material enters and leaves the chamber, and the chamber is connected via an outlet passage to a device which creates a sub-atmospheric pressure within the chamber. The sub-atmospheric pressure lowers the evaporation temperature of the cooling liquid which is on the surface of the material which evaporates and cools the material and the sub-atmospheric pressure causes air to flow into the chamber around the material in the region of the outlet and this airflow is at high velocity and wipes the material. The apparatus is preferably located on the end of a structure in which a drawing die is housed.
